# AI assistance may produce neurologically-grounded, partially irreversible skill degradation through three concurrent mechanisms: prefrontal disengagement, hippocampal memory formation reduction, and dopaminergic reinforcement of AI reliance

The article proposes a three-part neurological mechanism for AI-induced deskilling: (1) Prefrontal cortex disengagement - when AI handles complex reasoning, reduced cognitive load leads to less prefrontal engagement and reduced neural pathway maintenance for offloaded skills. (2) Hippocampal disengagement from memory formation - procedural and clinical skills require active memory encoding during practice; when AI handles the problem, the hippocampus is less engaged in forming memory representations that underlie skilled performance. (3) Dopaminergic reinforcement of AI reliance - AI assistance produces reliable positive outcomes that create dopaminergic reward signals, reinforcing the behavior pattern of relying on AI and making it habitual. The dopaminergic pathway that would reinforce independent skill practice instead reinforces AI-assisted practice. Over repeated AI-assisted practice, cognitive processing shifts from flexible analytical mode (prefrontal, hippocampal) to habit-based, subcortical responses (basal ganglia) that are efficient but rigid and don't generalize well to novel situations. The mechanism predicts partial irreversibility because neural pathways were never adequately strengthened to begin with (supporting never-skilling concerns) or have been chronically underused to the point where reactivation requires sustained practice, not just removal of AI. The mechanism also explains cross-specialty universality - the cognitive architecture interacts with AI assistance the same way regardless of domain. Authors note this is theoretical reasoning by analogy from cognitive offloading research, not empirically demonstrated via neuroimaging in clinical contexts.
